This invention relates to catch-basins and particularly to the outlet to a drain pipe leading to the sewer. v

An object of my invention is to provide a catch-basin, formed of a plurality of sections which, when fitted together, embody a discharge by-pass from the receiving chamber up to the outlet to a drain pipe leading to the sewer.

A further object is to provide a clean'out opening, communicating from said receiving chamber and providing easy access to said drain pipe and said discharge bypass.

A furtherobject of my invention is to provide a catch-basin, formed of a plurality of sections which, when fitted together, embody a discharge by-pass from the receiving chamber up to the outlet to a drain pipe leading to the sewerand a clean-out openingat a higher level than the bottom edge of the outlet, yet in such alignment with said drain pipe as to permit horizontal manipulation of rods from the receiving chamber for cleaning out said drain pipe.

lVith the foregoing and other objects in view as will appear as the description proceeds, the invention consists of thenovel construction, combination and arrangement of co-operating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming a part of the present application.

The accompanying illustration discloses a cross sectional view of the preferred embodiment of my invention.

In the accompanying drawing, I have shown four sections A, B, C and D, which are substantially of hollow tile formation and I may be made of any desired material suitable for the purpose, the different sections be i119; provided with interlocking connection.

The section D is provided with a bottom E. The sections A, B and C have at one side an outwardly protruding portion S in which is formed a discharge by-pass F, the lower end of which (as at G) communicates with the central receiving chamber I-I below the normal fluid level thereof, which level is indicated as at I. J is a clean-out opening formed above the normal fluid level I and preferably BAsnv- 1929. SerialNo. 344,501.

in vertical alignment above the lower end G of the bypass F. The by-pass F and the clean out opening J jointly communicate with the discharge opening K.. This discharge opening K is provided with an enlarged receiving socket for receiving the end of the drain pipe L, which drain pipe L leads to the sewer. Around the clean-out opening, I provide a casing M, having a door N suitably hinged in combination therewith to normally close the clean-out opening J.

In the illustration annexed herewith, it will be noted that the lower edge 0 of the cleanout opening J is above the lower edge P of the dischar e opening K, yet at the same time below the upperedge Q of-the discharge opening K. On acco'untof this relative position of the respective openings and by-pass, the surface fluid in the central receiving chamber H will normally flow up through the discharge by-pass F and off through the drain pipeL'to the sewer. Under normal conditions the sediment will settle in the sectionD. When the sediment fills up to a level above theopening G into the by-pass F, the

flow of fluid will be'cut off. The door N (normally closed) will stop any flow of fluid through the clean-outbpening J. The surface water from the street coming into the catch-basin will fill the central receiving chamber. Eventually, one of thecivic employees will remove the accumulated sediment, which when removed will allow the sediment in the discharge by-pass F to backflow into the central receiving chamber II. If this sediment is packedtoo solidly or frozen in the by-pass F,the employee may open the door N and insert a clean out tool or steam line. A

From the experiments which Ihave made, there is little or no possibility of the drain pipe L'becoming cloggedwith solid sediment or foreign matter, but if such should be occasionedat any time, my disclosure provides a clean-outopening J, the lower portion of which is inhorizontal alignment with the upper portion of the drain pipe F, so that inthis way ready access may be had for using the required tools or rods for the cleaning out of the drain pipe L.

A further advantageous featureof my construction is that the central receiving chamber is preferably of annular formation and has no inwardly projecting parts, elbows or connections which would obstruct and hinder the proper cleaning out of sediment or foreign matter from the bottom sections of the a ch-bas i In the sections illustration, I have disclosed what I consider the formation the ditlerent spe lings the discharge by-pass in a manner which would be the easiest for casting. These open: ings and the by-pass may be formed in other relative positions from that disclosed in the illustration without departing from the spirit and scope of the inventionas claimed. It

may be found advantageous to have these openings and the by-pass cast as a separate uni t 'b fi ed Onto th si o a t h-b si V which is in use at the presenttime so as to transform it into a discharge trap system with clean-out facilities similar to'tha't disclosed 'hereinbefore,

The foregoing specification and annexed drawing disclose the preferred embodiment of my invention, but it is-to he understood hat min h g s may be r s r d o in h omme ial adapta of my in en ion Wit out. departing from the, scope of the invention as hereinafter claimed. i

What I claim as new is As an improved article of manufacture, a catch-basin of separately-moulded, interlocking sections adapted to be built upon each other to make a complete unit, one of said sections providing a closed bottom for, said unit, one of said sections having an integral lip o t a ly e med at one side he of, another of said sections having an integral portion outwardly formed at oneside thereof and 7 a p ed t9 r g s n nt r cking e g ge I merit over said'lip, another of said sections having an integral cap outwardly formed at onesidethereofand adapted to register in interlocked engagement over said portion, a drain-pipe opening being formed inwardly of the out-er contour'of said portion andsaid cap at the junction thereof, a by-pass opening formed in communication with said drain.-

pipe opening, downwardly through said portion and communicating with the interior of said unit at the junction of said portion and said lip, a clean-out opening formed in said eap a i j n ti n ith said p rt on nd commun ng fr m th in erior of said u it t said a n-P p P n ng nd Wi ht e pp r end of said by-pass opening and. a closure member for normally closing the inlet to said clean-out opening. 7
